Hello,
I'm currently playing a LAN game with my friend on my singleplayer world. Every time, we interact with a sliding door, it's fine for me (as a host), but for him, it crashes his game.

His crash report: https://paste.dimdev.org/qubaxosuqe.mccrash
Video example: https://youtu.be/ZHH7-fyLRe8

This will be fixed in the upcoming version.

New version has been released.
